Issue Details

Steps to reproduce:

1. Install AdGuard on a Samsung device
2. Start protection
3. Check what notifications it shows

Expected Behavior

It shows a notification about compatibility issues with the Korean phone version.

We should not bother users of all other Samsung phones.

Actual Behavior

We should only show this notification to Korean users only.

There was an argument that this may be a Korean version of the phone used elsewhere.
However, it appears that the Korean Samsung Pay works in South Korea only [0] so this argument is not valid, the users won't be able to use such app anyways.

How we can detect Korean users? I suggest using keyboard layouts for that, just like we detect what filter lists should be enabled.
